A member in my Sunlineclub.com had his fridge go bad. He did some reseach and opted to replace the cooling unit. Here is a link to where he got the unit:

Sorry, laptop acting stupid, can't make it a true clicky link.
When my fridge quit I looked into having the cooling unit replaced and decided to go with a new one for 3 or 4 hundred $ more. I changed it myself. Not an easy job as the MH door had to come off to make an opening large enough to get the fridge through.
